Found a weard thing.. Seems my alternator is not a lucas one but a Magneti Marelli one... MAybe because its a european car?

I know Magneti Marelli supply parts for Italian cars, as my alternator in my Fiat is also made by them. 

 

Jep, his fiat ritmo(strada)'s have them also :P identical casting but different internals ( sadly :D )

Small question : om running a electric fuel pump and I have 4 55watt spots.
What alternator should I pick? 45,55 or 70 amp?
Will I need upgraded wiring with a 70 amp alternator?

W=VxA 

 

so 220W of lights divided by 12 means an extra 20ish amps of drain, the 5is amps the fuel pump needs should be within the capabilities of the original alternator. The wiring should be fine, it's just the run (usually 2 thick brown wires) from the alternator to the solenoid's battery terminal, but yours (and the connector) may be different.
